FASHIONING KNITTING-MACHINE.

Specification of Letters Patent.

Patented Oct. 17, 1905.

Application filed July 20, 1903. Serial No, 166,284.

To all whom, it may concern:

Be it known that I, HENRY JANssEN, a citizen of the United States, residing at VVyomissing, county of Berks, State of Pennsylvania, have invented certain new and useful Improvements in Fashioning Knitting-Machines, of which the following is a specification.

My invention relates particularly to knitting-machines of the cotton or fullfashion type; and it consists in the improved manner of mounting and controlling the operation of the slur-cam shaft, through the medium of which the sinker mechanism is suitably operated during the ordinary knitting operation or thrown out of .action during the narrowing or fashioning operation as determined by the movement of the main cam-shaft.

The invention is fully described in connection with the accompanying drawings and the novel features are particularly pointed out in the claimsi Figure 1 is a partial cross-sectional view of a machine having my improvements applied thereto. Fig. 2 is a partial front view of the same. Fig. 3 is a plan view of the connecting frame, showing the bevel gear-wheel in crosssection.

A and A represent the longitudinal framebeams, B the main cam-shaft running parallel therewith, and O the transverse slurcam shaft arranged, as shown, in the same horizontal plane as the cam-shaft and at right angles thereto. The frame-beam A along the front portion of the machine lies in a lower plane than the rear frame-beam A and the cam-shaft in a vertical plane between the two beams, as usual. 1

Inasmuch as my improvements relate eX- clusively to the mounting of the slur-cam shaft C and the operation of the same as controlled by the main cam-shaft B of the machine, it is unnecessary to illustrate or specif ically describe those parts of the machine which do not bear upon my invention and which may be such as are commonly em ployedin this class of machine. It is only necessary to mention that the cam-shaft B is provided as usual with narrowing or fashioning cams adapted to carry and operate the through the jacks operate the sinkers to form the loops, all as usual in this class of machines and the showing of which is unnecessary, and therefore omitted.

The main object of my invention is to provide for securing at all times a uniform and reliable connection and disconnection of the slur-cam shaft with the longitudinal camshaft without subjecting the parts to unnecessary shock or wear. To this end I employ a-carrying-frame 1 for said slur-cam shaft eX- tending between and rigidly connecting the frame-beams A A, said frame being provided with suitable bearings 2 and 3 for said slurcam shaft, the latter located adjacent to the rear face of the bevel-gear 4, which is fixed to the projecting forward end of said shaft, and being extended beneath said bevel-gear 4 and the longitudinal cam-shaft B to its con nection with the forward frame A. This frame 1 carries also, as shown, a brake mechanism for said slur-cam shaft and a holding device 5 for the loose bevel-gear 6 on the cam-shaft, which serves to retain said gear constantly in mesh with the bevel-gear 4 on the slur-cam shaft. This bevel-gear isv either rotated with the cam-shaft B or not, depending upon the longitudinal movement of the latter, already referred to, a toothed clutchcollar 7 being fixed to said cam-shaft, so as to rotatively engage the outer face of the loose bevel-gear whenever said shaft is so moved as to throw the narrowing-cams thereon out of operation, and to be disengaged therefrom when it is so moved as to throw said narrowing-cams into operation.

Whenever the cam-shaft B is moved longitudinally to throw the fashioning mechanism into operation, the clutch 7 is by such movement thrown out of engagement with the pinion 6, as stated, and though the latter is still retained in mesh with the bevelgear 4 of the shaft C by the holding device 5 it (the pinion 6) will no longer control the movement of said gear 4. For this purpose I provide the improved stop mechanism shown, which is arranged to be operated by the same longitudinal movement of the camshaft that disengages the pinion 6 therefrom, a collar 8, fixed to said shaft, being adapted to contact with one member 9 of a-suitablymounted rock-arm 10, so as to turn the latter, and thereby swing its other member 11, to which is attached a brake-band 12, encircling a brake-wheel extension 13 of the bevelgear 4, as shown. The rock-arm member 9 is provided with an end roller 14, against which said collar 8 on the cam-shaft presses during the longitudinal movement of the latter referred to and which is free to be rotated by said rotating collar at the same time that it is being swung, thereby to apply the brake. This braking action should be effective promptly, but at the same time without jar and undue wear, and to secure this result I connect the brake-band 12 to the rock-arm member 11, as indicated, one end of said band being rigidly secured to a side lug 15 thereon located intermediate of the length of the member and the other end being adjustably and yieldingly secured to the extremity thereof by means of a transverse turn-bolt 16 in said member, an adjustable connectingscrew 17 passing through the head of said turn-bolt, and a spring 18 on the projecting body of said screw inclosed by a sleeve 19 and arranged to yield somewhat under the braking action, and thereby avoid a jarring stoppage of the slur-cam shaft C, while at the same time definitely controlling its movement. The rock-arm 10 is mounted above the bevel-gear 4 in a bearing formed at the top of a bracket 20, which is removably secured to the carrying-frame 1 underneath the cam-shaft B. The bevel-gear 4 on the transverse shaft C, as shown, has a brakewheel 13, formed integral therewith, as well as a counterbalance (indicated at 21) for the slur-cam D, said counterbalance being within the wheel-rim 13 and arc-shaped, so as to swing clear of the bearing 3, which is thus carried well out toward the end of the shaft 0.

The purpose and effect of my improvements just described have already been clearly stated.

The preferred construction specifically shown and described may obviously be modified without departing from the invention.

WVhat I claim is 1. In a fashioning knitting-machine the combination with the longitudinallymovable cam-shaft carrying a loose bevel-gear transverse sinker operating shaft carrying a meshing bevel-gear, of a carrying-frame for said transverse shaft bridging and rigidly connecting said beams and a stop mechanism for said meshing bevel-gear carried by said transverse frame and in operative engagement with said longitudinally-movable cam-shaft.

3. In a fashioning knitting-machine having parallel longitudinal frame beams, the combination with. the longitudinally-mow able cam-shaft carrying a loose bevel-gear and an engaging clutch therefor, and the transverse sinker-operating shaft, of a meshing bevel-gear on the latter carrying a brake wheel, a rock-arm having one member in operative engagement with said longitudinallymovable cam-shaft, a brake-band carried by the other rock-arm member, a carryingframe for said transverse shaft bridging said beams underneath the cam-shaft, and a sup porting-bracket for said rock-arm secured to said carrying-frame below the cam-shaft.

4. In a fashioning knitting-machine having parallel longitudinal frame beams, the combination with the longitudinally-movable cam-shaft carrying a loose bevel-gear and an engaging clutch therefor, and the transverse sinker-operating shaft, of a mesln ing bevel-gear on the latter carrying a brakewheel, a rockarm having one member in operative engagement with said longitudinallymovable cam-shaft, a brake-band carried by the other rock-arm member, a carryingframe for said transverse shaft bridging said beams and a supporting-bracket for said rock-arm and a holding device for said loose bevel-gear secured to said carrying-frame.

5. In a fashioning knitting-machine the combination with the longitudinally-movable cam-shaft carrying a loose bevel-gear, an engaging clutch therefor, and a brakeoperating collar, and with the sinkeroper ating shaft, of a meshing bevel-gear on the latter carrying a brake wheel, a suitablymounted rock-arm having one member provided with an end roller arranged to engage said collar, and a brake-band carried by the other rock-arm member.

6; The combination with the longitudinal cam shaft of the transverse shaft driven thereby and carrying at one end thereof the s1ur-carn and at the other end abevel-gear having a brake-Wheel extension With oounterbalance for said cam formed integral therewith a brake-band on said Wheel and means for operating the same.

In testimony whereof I affix my signature in the presence of tWo wltnesses.

HENRY JANSSEN.
